Gut bacteria may reveal how a Western diet fuels colon cancer via bile acids

New research suggests that gut bacteria may be the key link between a Western diet and the development of colon cancer, with diet-driven changes to bile acids in the gut appearing central to the mechanism. A diet high in fat and processed foods alters the composition of bile acids, potentially creating conditions that promote tumour growth. The findings could open new avenues for cancer prevention and treatment strategies.
